Toy problems
************

The `toy` module provides toy :class:`models<pints.ForwardModel>`,
:class:`distributions<pints.LogPDF>` and
:class:`error measures<pints.ErrorMeasure>` that can be used for tests and in
examples.

Some toy classes provide extra functionality defined in the
:class:`pints.toy.ToyModel` and :class:`pints.toy.ToyLogPDF` classes.
